| 空気の代わりに酸素を用いてコークスを燃焼させ、CO、CO2、およびH2を含み、過剰窒素を含まない炉項ガスを高炉の上部から抜き出し、ダストを除去し、水性シフト反応器内でH2/COの体積比を1.5〜4.0の範囲に調整し、水およびCO2を取り除き(その還元能力を増加させる)、850℃を超える温度になるまで加熱し、鉄が熔解し始めるよりも高い位置で高炉に戻す(これにより、金属鉄がデッドマンゾーンに到達する量が増加し、還元に利用されるコークスの量が減少する)。CO含有再利用ガスを加熱することで生じる炭素付着の問題についても、蒸気を用いたヒータチューブのオンライン洗浄により、再循環された還元ガスの還元能力に著しい悪影響を及ぼすことなく、最小限に抑えられる。 | ||||||

CONSTITUTION: At the time of blast starting from the blast-stop of blast furnace 1, cut-off valves 15W17 are closed and the exhaust gas for blast furnace is passed through the bypass pipe 31, to adjust the pressure in the blast furnace 1 by the flow control valve 33 for the scrubber 32 and the waste gas is treated by the scrubber 38, to flow the gas washer 18. At the time of completing blast starting from the blast-stop, the cut-off valves 15W17 are opened and at the same time, the control valve 33 is closed and so it is shifted into the usual operation, which the waste gas is sent to the washer 18 from a coarse particle dust catcher 5, dry-type dust collector 10 through dry-type furnace top turbine 12. Further, at the time of blast furnace 1, the increasing waste gas by opening control valve 33 for the scrubber 32 is sent to the washer 18 after treating by scrubber 32 from the bypass pipe 31.
